Nutrient Management: Nitrogen
Nebraska Extension has many tools and resources for interpreting soil tests. Most of the materials do not focus on one nutrient, but discuss all the nutrients related to a specific crop.
One regional publication focuses on nitrogen specifically:
Agricultural Nitrogen Management for Water Quality Protection in the Midwest: a Heartland Regional Water Coordination Initiative Publication RP189; PDF* ( 1.85 MB; 32 pages)
Our complete nutrient management guide explains each nutrient and gives recommendations for each crop:
Nutrient Management for Agronomic Crops in Nebraska Extension Circular 155
